[Epidemiologic follow-up study of cancer and borderline lesions of uterine cervix].

Follow-up results of 329 cases, who were recommended for colposcopy and biopsy after uterine cervical cytologic tests among 38,610 screenees in Shiga Prefecture 1986, were studied. 41 cases (12.8%), including 26 CIS cases, were diagnosed as cervical cancer. 102 cases (30.7%) belonged to dysplasia and other lesions, such as erosion and chronic cervicitis, were 155 cases (47.1%). Only 8 screenees (2.4%) were lost in follow-up. Close follow up for borderline cases may be enough if dysplastic lesions do not progress for over 3 years.
